Fast growth of undoped and Sn and Tb doped ZnO nanowires by Joule heating of Zn

Abstract

Joule heating of Zn wires by the flow of a high electric current density has been used to grow, in times as short as tens of seconds, undoped and Sn or Tb doped ZnO nanowires. The contact of tin oxide powder with the starting Zn wire during heating leads to the growth of branched ZnO nanostructures by a catalytic effect of Sn. The growth treatment in presence of terbium oxide gives rise to a complex ZnO arrangement of nanoparticles attached to nanowires, which show luminescence emission of Tb3+ transition due to incorporation of small amount of Tb into the ZnO nanoparticles during the growth process. The contribution of electromigration, associated to the high electric current density, to the rapid growth of the nanowires, as compared with other thermal based techniques, is discussed
